If you are finding that your device's Ethernet connection no longer works

Should you use an anti-virus like Symantec Endpoint Protection, if the device is present and working in Device Manager, please check that the LAN connection exists. If that connection is missing, then reinstall the driver without the anti-virus blocking the creation of the network adapter in Windows.
